Patented May 15, 1923.

HENRY J. SHAVERS, OF GOLDSBORO, NORTH CAROLINA.

LUBBICATOR.

Application filed October 31, 1921. Serial No. 511,771.

To all 'whom t may concern.'

Be it known that HENRY J. SHAvnRs, a citizen of the United States, residing at Goldsboro, in the county of Wayne and State of North Carolina, has invented certain new and useful Improvements in Lubricators, of which the following is a specification.

My invention relates to new `and useful improvements in lubricators that are especially designed to force heavy oil and graphite to the cylinders 0f a locomotive.

The present invention is somewhat similar in type to the lubricator shown in Patent No. 1,384,353, granted to me on July 12, 1921.

In the patent just above mentioned the oil and graphite were placed in one main reservoir and then forced by the same means to the cylinders of the locomotive, while in the present instance separate reservoirs are provided for the reception of the oil and graphite and separate means are provided for forcing the oil and graphite to the cylinders of the locomotives.

One of the objects of the present inven-v tion is to provide a lubricator wherein the graphite will be continuously under a slight pressure and will be constantly agitated in the reservoir by a revolving blade which is designed to scrape the lower sides of the reservoir so that the graphite may be properly fed to the regulating means which is located just below the blades, this regulating means determining the amount of graphite to be fed to the cylinders by each stroke of the plungers of the lubricator.

Still another object of the present'invention is to provide this regulating means in thev form of a rotary shaft which is placed beneath the graphite chamber, this shaft having formed therein oppositely disposed pockets for the reception of the graphite from the reservoir which pockets in turn permit the discharge of the `graphite to the plungers of the cylinders, the shaft being in synchronism with the said plungers.

Still anotherobject of the invention is to form this shaft with the disposed pockets mentioned and to provide passage ways eX- tending laterally to these pockets, in which are placed regulating tubes which are capable of adjustment so that the capacity of the pockets may be made greater or less depending upon the amount of advance or retraction of these tubes.

Still another object of the invention is to provide means for supplyingV oil to the cylinders of the locomotive which may be used 1n conjunction with the flow of graphite or may be used in an auxiliary manner.

lWith these and other objects in view, the invention consists of certain new and novel arrangements and combination of parts as wili be hereinafter more fully described and pointed out in the claims.

' Referring now to the drawings showing a preferred form of the invention:

Fig. 1 is a side elevation of my improved lubricator, parts being shown in section and others in elevation, Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1 looking in the direction of the arrows, some of the parts being shown in elevation,

Fig. 3 is a detailed sectional view of the regulating` shaft and Fig. i is a top plan of the main driving crank, the outer sprocket being shown in section.

Referring now in detail to the several figures, there is shown a base 1, on which is mounted a motor 2, although it is to be understood that any form of driving means may be employed. A standard 3 is shown in which is mounted the crank shaft 3 on which is mounted the worm gear a which in turn is driven by the worm gear 5 on the motor shaft. A sprocket 5 is mounted at one end of the crank shaft 3 as clearly shown in Fig. 4.

Two crank arms 6 are operated by the gear 4 to which crank arms are in turn secured the connecting rods 7, the same in turn being pivotally mounted to the cross head 8, which is mounted on the sliding bar 9.

This sliding bar is supported at one end by the standard 10 and at its other by the main housing 11 of the lubricator.

This housing 11 is in turn supported by the brackets 12 which are bolted to the base l as clearly shown in Figs. 1 and 2.

Mounted in this housing are the two cylinders 13 and 14 to which are bolted the heads 15 and 16, and as the cylinders and heads and cooperating plungers are identical a description of one will suffice.

Referring now in particular to Fig. l it will be seen that the head 1.6' extends inwardl-y for a greater portion of the cylinder, and is provided with the rings 17, and lis beveled at its inner end, and provided i with the projecting portion 18.

Within this cylinder is the hollow plun ger 19 which is provi-ded with the upper or inlet port 20 and with the larger outlet port 21 formed in its under suritace. Connected 13 to this plunger is the rod 22 which extends through its cylinder head 23 and the gland 2l and is fastened to the heretofore inentioned sliding head 8.

This hollow plunger snuglyiits the head "13 16 so that when the saine is operated it will compress the air in the plunger on its forward strokD and form a vacuum on its rearward or return stroke.

Extending througlrthe lower portion of 20 the cyrincer is the port 25 and directly beneath the saine is the check Valve 26 secured in turn to the coupling 27 ir one side of which may he secured a jet. pipe 28 while another pipe 29 leads to the cylinder of the 'l5 locon'iotive. Also leading to this coupling 2T (Fig. 2) Ais the pipe 30 whicn is from the oil feed as will be hereinafter described.

ris far as the description has proceeded it follows exactly the construction shown in :10 my former patent with one exception, that is, on the main crank shaft there is mounted the sprocke 5 as heretofore mentioned and the purpose of which will beshortly described. p 35, Referring now tolFigs. l, 2, and 3, it will be seen that bolted or otherwise secured to the housing 11. is the graphite reservoir partly in the form of a cylinder 81. in which is provided the small piston head 32, and in t0 a cylinder head 33 is secured a small pipe 34 for' the admission of a slight amount of steam yor airpressure. A packing gland 35 is also secured" centrally Vto the head through which entends the/tube or hollow '45 shaft 36, on which is mounted the heretoi 1 it will be seen that when `the lubricator is forenientioned piston khead 32. This hollow shaft and piston are slidingly mounted on a main vertical shaft 37 which extends from the lower` end of the reservoir and to the standardl 38 and is provided near its upper end with a 'beveled gear 39 which in turn meshes with the gear LOwhich is Inioun'ted l on a stub shaft 411, said shaft being suitably mounted in the bearings .42 formed on the "5' upper part ofthe standard 3S, and a small sprocket 43 is mounted on the stub shaft `as shown in Fig. 2. To the lower end of the vertical shaft 87 are 'secured the vanes or blades 48 which extend parallel with the G0 lower inner side walls of the reservoir, these nwalls beingibeveled or truncated .as clearly 'shown in the separate figures. The lower en'd of the shaft 37 may be notched as at L9 to also assist fin'cutting or disintergrating "the graphite. i

Kis retracted.

A main discharge opening 50 is provided centrally of the reservoir and at its bottoni extending laterally7 through the base of the reservoir is the bearing 51. in which is rotatably secured the regulating shaft 52, which is provided with a slightly enlarged central portion 53 in which is disposed the oppositely disposed pockets 5l and Two passage ways 5G and 5T are shown which respectively extend from the outer ends of the shaft to the pockets which passage ways are angularly disposed to the central axis ot' the sl aft. These passage ways are internally threaded for the reception of the reguloting tubes 58, one being shown in an advanced position in Fig. 3.

rllhe purpose of these regulating tubes is that when they are advanced the capacity of the pocket will be less than when the tube Lock nuts 59 are providedso that the tubes may be held in an advanced or retracted position. Small check valves 60 are provided on 'the outer ends of these tubes so that air may hef drawn through in the tube, but cannot be forced therethrough.

@n this regulating shaft there is provided tivo sprockets 6l and t2, the sprocket 51 carrying a chain .G3 'which vpasses over the sprocket i3 mounted on `the'stub shaft al while the outer sprocket G2 is ydriven Aby a chain extending toV the' sprocket 5 on the crank shaft 3.

The outer sprocket 62 and the sprocket 5 are each provided with the requisite number of teeth, so that a complete forward and rearward stroke of the plungers ywill cause a complete revolution'of thel regulating shaft Located just below the regulating shaft 52 is a further lateral passage 66 provided with slight glasses at each end so that the discharge ofgraphite may be seen and regulated.

As far as the specification has proceeded in operation the vertical shaft 37 with the blade 48 thereon will be constantly revolved as wellas the rotatable regulating shaft 52,

land as onerof the pockets register with the opening 50 of the reservoir it will be 'filled 4with graphite and then revolved'to the discharge position where the suction caused by the rearward stroke of the plunger will draw the graphite from the pocket down intothe hollow plunger, this being made possible by' 'havingthe regulating tubes hollow and provided with check valves to allow a` slight amount o f air to be drawnwith the graphite. lf a less amount of graphite/than the capacity of a whole pocket is desired, the tubes will be advanced to thereby lessen the capacity kof the pockets.

Referring now to the means of furnishing the oil tothe cylinders, it will be noticed discharges for the oil chamber is at shaft will be made so that the that the reservoir 3l 'is provided with. the

opening TO andplug-YL at its bottom, and the opening 72 and plug ?3 at its top and with a central inlet passage 74 which registers with the discharge opening 75 of a condenser 76. A pipe 7T is threaded into the top of this chamber 69 and extends nearly to the bottom thereof while the main 80, these discharge openings being located in the top of the chamber.

From these openings leads the pipes 82 which in turn extend to sight chambers S3 which are provided with valves Se while from the top of these chambers aretlie elbows 85 which are connected to the pipes 30, heretofore described which extend into the couplings 27.

Oil will be placed in the chamber 69 and 20 as the water or condensation arises in the chamber, the oil flowing to the top will be forced out through the outlets or opening 8O to the chambers 88 which will alsoV become filled with water and the oil may then be noticed as it passes through the water to the pipes 85 and to the couplings 27. This is the usual practice of yfeeding o il to the cylinders of a locomotive. Separate arms 86 are shown bolted'to the main casing for supporting these sight chambers.

The arrangement and operation for feeding the desired amount of graphite has been set out and 1t is to be understood that the oil will generally be fed to the cylinders in conjunction with the graphite.

From the foregoing it will be seen that the desired amount of graphite to be fed to the cylinders may be quickly and easily regulated and as a complete stroke of each plunger is made a complete revolution of the grahpite will l i first forced into the upper Vpocket of the shaft 52, which pocket will be then revolved to its discharge position, the return stroke of the plunger causing the vacuum which will draw the graphite into the plunger. Again on the forward stroke of the plunger it will force the graphite into the main pipe extending to the locomotive cylinders and at the same time revolve the pocket to a receiving position.

The revolving blades agitates the graphite at all times and insures the constant and proper feed to the pockets. Also by providing hollow regulating tubes a sufficient amount of air is admitted to the pockets so that the graphite may be withdrawn therefrom by the rearward action of the plungers, and the amount of graphite may be regulated according to the set position of the tubes. p

Many slight changes might be made in the arrangement and positioning of the parts without in any way departing from the spirit and scope of the invention.
